His mentality the past week from so has been such a departure from what we've seen from him previously, I'm almost 100% certain it's not because of Visma's tactics, or the race being hard, or him generally hating GTs. I think he generally doesn't appreciate the dangerous way of riding of the current era, which was best exemplified in the first 11 stages, so to be taken out by an insane move in the last 5k of that stretch probably was very frustrating. Add to that the obvious cold (importantly which Vingo didn't get), combined with the weather suddenly becoming terrible, and you have and almost worst case scenario, which drained him in every aspect and was undoubtedly very unpleasant. I still feel, barring there being some external political reasons, if he doesn't catch the cold, he wins 7 stages and leads by 7 minutes. In comparison, last year, even though he was also drained after the tour, the positive mentality was there all the way and he won the last 3 stages.
I mean, it's basically that, or he somehow suddenly developed an early-life crisis in the middle of this tour out of nowhere.
